BOILER-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 625,207, dated. May 16,1899.

Application filed April 4,1898. Renewed March 15, 1899. Serial No.709,200. (No model.)

To all whom it may concern:

Be it known that I, GoTTLoB F. SoHMID, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented new and useful Improvements in Boiler-Cleaners, of whichthe following is a specification.

Myinvention relates to improvements in automatic boiler-cleaners, andhas special reference to improvements in the device shown in LettersPatent No. 511,064, granted .to me December 19, 1893.

The present invention consists in certain novel featureshereinafterfirstfnllydescribed and then specificallypointed outintheclaims.

In the drawings, Figure 1 is a perspective view of my improved cleanerattached to a water-tube boiler, parts of the wall and the steam-drumbeing broken away. Fig. 2 is a view showing the manner of attaching thecleaner to a series of boilers. Fig. 3 isaview of thecleanerdetached,showin g a slight modification; and Fig. 4 is a detail view ofthe pan.

In carrying outmyinvention I employ three drums or cylinders A A A thelower horizontal drum A being provided with a blow-0E cook or valve B,as shown. Above the'drum A is arranged the smaller horizontal drum A,which is connected with the drum Abya short pipe or coupling 0. A pipeD, leading from the steam-drum of the boiler, enters the end of thesediment-drum A at the end opposite the blow-off cook or valve and isprovided at a convenient point with a valve E. Just before it enters thedrum the water-pipe D is joined by a mud-pipe F, also leading from thesteamdrum of the boiler and provided with a valve G. These pipes D and Fare connected with a pan H within the steam-drum, to which the water issupplied by the feed-water pipe I. This pan is supported on the bottomof the steam-drum by suitable legs or brackets in an inclined position,so that the Water will be forced to flow toward the back end of the panand cannot stagnate therein. The top of the pan is open, except at thelower end, where it is provided with a skimming-plate J. This plate Jserves to skim or separate the impure water containing the heavysediment or impurities from the less impure water.

purer water will pass over the plate and into the water-pipe D, which isconnected to the boilers.

The

pan at the rear end of the same and just above the lower edge of-theplate, while the heavy impurities and mud will be deflected into themud-pipe F, leading from the bottom of the pan. This partial separationand precipitation of the impurities is accelerated by the heating of thefeed-water, which occurs in the steam-drum.

From the pan the water and mud are carried into the sediment-drumA,where the mud and other. impurities are deposited on the bottom, thewater rising into the reservoir-drum A, where it is collected. In thisreservoir-drum there will be a still further purification of the water,as the impurities remaining therein naturally settle at the bottom. Fromthe top of the reservoir-drum an elbow-pipe K leads into the verticaldistributing-drum A at a point near the top of the same, and at the bendof the said pipe K, I connect the end of a steam-pipe L, leading fromthe steam-drum of the boiler and provided with a Valve M.

From the top of the distributing-drum a pipe N, having a valve 0, leadsto the mud-drum of the boiler,so as to convey the purified waterthereto. From the mud-drum the water circulates through the boiler inthe usual manner. The bottom of the distributing-drum is connected withthe top of the sediment-drum bya short pipe P, provided with a valve. Q,and the blow-off cock B may discharge into the open air, or, aspreferred, into a suitable waste-pipe. The efficiency of the device willbe increased if a valved connection be made between the returnwater-pipe N and the Waste-pipe; but this connection is not necessary.

If the cleaner is to be used in connection with a series of boilers,thesteam-pipe is provided or formed with a series of branches R, leadingfrom the steam-domes of the several The return water-pipe N will lead toa branch pipe S, communicating with the mud-drums of the several boilersand provided with check-valves T, so that the water may flow readily toeach boiler, but cannot flow from one boiler to another. The branchpipes will also be provided with valves U, so

that the water may be shut off from any boiler of which will be providedwith a valve V to control the flow of the water and cut out any oneboiler without interfering with the use of any of the others.

If the device is to be applied to a boiler of the ordinary pattern, thepipe D will lead from the boiler near the Water-line and the returnwater-pipe will enter the same at or near the bottom thereof, the panand the mudpipe being omitted.

The operation of the device will be readily understood. The Water entersthe pan and, being there raised in temperature, will be partly relievedof its impurities, which will flow separately to the sediment-drum. Inthe sediment-drum further purification will take place and the waterwill rise into the reservoir-drum, the impurities tending constantly tofall to the bottom of the Water. From the reservoir-drum the Waterpasses into the distributing-dru m and thence into the boiler, as willbe readily understood. WVhen it is desired to remove from the cleanerthe impurities collected therein, the valves E, G, and O are closed andthe valves B Q are opened. Steam will then pass from the steam-pipethrough the several drums and drive the accumulation therefrom and outthrough the blow-off cock into the waste-pipe.

By connecting the steam-pipe directly to the elbow-pipe I secure theaction of the steam-pressure directly on the accum nlations in thereservoir and sediment drums, where the deposit is greatest, andconsequently obtain a rapid cleansing of the drums.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

l. A cleaner for steam-boilers consisting of a sediment-drum providedwith a blow-0E cock at one end, a feed-Water pipe leading from theboiler to the opposite end of the sediment-drum, areservoir-drum abovethe sediment-drum and connected therewith, a distributing-drum above thesediment-drum and having a valved connection therewith, a pipeconnecting the reservoir and distributing drums, a steam-pipe connectedto said pipe and leading from the steam-space of the boiler, and areturn Water-pipe leading from the dis-. tributing-drum to the boiler.

2. The combination with the battery of drums-consisting of asediment-drum, a.rescr-.

voir-drum and a distributing-drum suitably connected, a pipenonveyi'ngthe water from the distributing-drum to the boiler, a steampipe adaptedto convey steam from the boiler to the drums, a pan within thesteam-drum of the boiler, a feed-water pipe leading into the said pan, awater-pipe leading from said pan to the sediment-drum, and a mud-pipeleading from the pan to-the sediment-drum.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
